I keep getting sim regestration failed even though i have a new sim what can i do to fix this issue?

Contact support and request a new activation code, you can not use the older one, because is already used, ask to resend a new activation code. Hope this help.

Try other company sim-cards......if they work....then try other docomo sim...if this works ur sim is faulty........get a new sim.......if ur set reads other co sim and not docomo....its ur sets fault.......u will have to change FEM(N2700 in pic.) ic...(as it has inbuilt duplex er i.e. antina switch which can cause this fault)... this ic can be obtained from a dead Nk2700....


There is another way to confirm this without dismantling ur set........switch on ur set with sim....ignore sim reg fail message.....go to menu>settings>phone settings>network>change this to manual >ok......now ur phone should search for network.....if it does not then either ur sim has fault or sim section......if it starts searching then let it search......after some time network service provider list will appear....on the top it should be tata docomo......if its not there then FEM ic to be replaced.....if it appears select it......if now sim registeration fail appears ....for ur and other tata docomo sim...then get software of ur set reloaded......if only ur docomo sim fails...get sim replaced

you can contact the service provider..........

Try another sim card. If that does not even help then try to Flash the phone and change the uem. Your local phone dealer will be able to do that for you.

When SIMs get a bit old, they get a little worn down and the contacts can get dirty or the fit may become a little loose over time.
Take the SIM out and clean it gently, but don't use any chemicals.
If the SIM fits with a flap that clicks over it, put a pieve of paper over the SIM to make the fit tighter. Make sure the metallic contacts are not covered, just the back.
If this fails, try asking your phone network for a replacement SIM. There may be a small charge for this, but you will keep your number.
Remember to backup all your contacts before you swap your SIM to the new one!

Perhaps there is some loose connection of the SIM card to the SIM card holder and contacts. So remove the battery and the SIM card., Use a paper to polish the SIM card contacts and the contacts on the holder. Make sure that the SIM when placed fits well into the holder firmly and in place , If not you can lift up the contacts very carefully so that the SIM never loses contact.
If this wont solve there are errors in the main board which might need more attention with help from Nokia care.

Please wipe clean your sim card and get it retry. If still problem, your sim is crashed and need replacement

I just got a sidekick off the internet and I put my SIM card in the phone and it says no SIM card. What do I do? Anyway to fix whatever is wrong?

sim cards do fail sometimes , try a new sim card.
try your sim in another phone .
another possibility is dirt in the charging point / data cable connection.
